    <h1>RGraph: <span>Javascript charts library</span> - Adjusting your charts interactively</h1>

    <script>
        if (RGraph.isIE8()) {
            document.write('<div style="background-color: #fee; border: 2px dashed red; padding: 5px"><b>Important</b><br /><br /> Internet Explorer 8 does not natively support the HTML5 canvas tag, so if you want to see the charts, you can either:<ul><li>Install <a href="http://code.google.com/chrome/chromeframe/">Google Chrome Frame</a></li><li>Use ExCanvas. This is provided in the RGraph Archive.</li><li>Use another browser entirely. Your choices are Firefox 3.5+, Chrome 2+, Safari 4+ or Opera 10.5+. </li></ul> <b>Note:</b> Internet Explorer 9 fully supports the canvas tag.</div>');
        }
    </script>

    <div style="float: left"></div>
        <p>
            Since 24th May 2010 you have had the ability to adjust your so if you want to see the charts interactively. Currently the Bar chart, Line chart,
            Progress Bar, Rose chart and the Radar have this facility. Some chart types use multiple event handlers and as such
            are unlikely to work well with other dynamic features. The Line chart is an example of this, and whilst it does work
            with the context menu (and so the full canvas zoom), it is unlikely to work with other dynamic features.
        </p>
    
    
        <p>
            At the current time this feature on the Bar and Line charts doesn't work with X axis in the center.
        </p>
    
    
        <p>
            If your intention is to make some sort of interactive console, new HTML5 input types may also be of interest (for example the new <i>range</i> input type
            which gives you a "slider bar"). Eg (Chrome/Safari/Opera):
        </p>
    
        <p style="text-align: center">
            <input type="range" min="0" max="100" value="76" onchange="document.getElementById('range_result').value = this.value"/>
            <input type="text" id="range_result" size="3" value="76" />
        </p>
        
        <h4>Note</h4>
        
        <p>
            Since interactivly adjusting a chart involves completely redrawing it, having a lot of them on one page can cause
            slower updates. For this reason each example chart is on its own page:
        </p>
        
        <ul>
            <li><a href="adjusting_bar.html">Bar chart</a></li>
            <li><a href="adjusting_gantt.html">Gantt chart</a></li>
            <li><a href="adjusting_hprogress.html">HProgress bar</a></li>
            <li><a href="adjusting_line.html">Line chart</a></li>
            <li><a href="adjusting_radar.html">Radar chart</a></li>
            <li><a href="adjusting_rose.html">Rose chart</a></li>
            <li><a href="adjusting_thermometer.html">Thermometer chart</a></li>
            <li><a href="adjusting_vprogress.html">VProgress bar</a></li>
        </ul>
        
        <h4>DOM2 event handlers</h4>
        
        <p>
            In January 2011 all adjusting was converted to DOM2 event handling. This makes adjusting work much better with other
            dynamic features.
        </p>
